let off the throttle before you leave the jump.
If you are going to land wrong, gas it HARD. This has saved me many, many times. I am sure of it...
Trying to adjust mid air, by gassing or braking, only works on long jumps.
It is best to land slightly rear wheels first.
If you are going to hit your face on the bars, try to hit the pad. (Maybe practice aiming for the pad?!?) I hit my chin (no stiches, but still hurts) on the top of the throttle last thursday. I bit chunks out of both sides of my tounge. I can talk normally (my opinion) after one week now...
Don't jump with tounge hanging out.(see above)
This probably won't be heeded
; Don't let anybody talk you into something you probably won't be able to pull off in relative
Try to ride with someone who rides better than you as often as possible.
